Questions and Answers

What occurs in the presence of a positive externality and its effect on the optimal quantity of education?

The supply decreases, causing the price of education to fall.

The social value equals the private value at equilibrium.

The equilibrium quantity is equal to the optimal quantity.

The social value exceeds the private value, leading to a higher optimal quantity. (correct)

Which of the following statements correctly describes the relationship between QMARKET and QOPTIMUM?

QOPTIMUM is larger than QMARKET reflecting the total social value. (correct)

QOPTIMUM is larger than QMARKET because of private costs.

QMARKET equals QOPTIMUM in the presence of negative externalities.

QMARKET is larger than QOPTIMUM due to market inefficiency.

How does the alignment of private value and social value affect the supply of education?

There is no effect on supply regardless of the relationship between social and private values.

Supply decreases if optimal quantity is larger than market equilibrium.

The supply of education increases when the social value is less than private value.

An increase in supply occurs when social value exceeds private value. (correct)

Study Notes

Externalities & Market Inefficiency

Negative externalities occur when there is a cost to a third party not involved in the production or consumption of a good
The optimal quantity produced, QOPTIMUM, is smaller than the market equilibrium quantity, QMARKET
The government can internalize the externality by altering incentives so people take account of the external effects of their actions

Positive Externalities

Positive externalities occur when there is a benefit to a third party not involved in the production or consumption of a good
Examples include education, government, lower crime rates, and increased productivity and wages
The optimal quantity, QOPTIMUM, is larger than the market equilibrium quantity, QMARKET
The government can internalize the externality with subsidies

Technology Spillovers

A technology spillover is a positive externality
It occurs when a firm's research and production efforts impact another firm's access to technological advancements
The government can correct the market failure by providing a subsidy equal to the value of the technology spillover

Public Policies Toward Externalities

Tradable pollution permits are a market-based approach to solving the problem of pollution
Firms can voluntarily transfer the right to pollute to each other
Permits become a new scarce resource with a market to trade them
The firm's willingness to pay for a pollution permit depends on the cost of reducing pollution
Tradable pollution permits are efficient because firms that can reduce pollution at a low cost will sell permits and firms that can reduce pollution at a high cost will buy permits

Private Solutions to Externalities

The Coase Theorem states that if parties can bargain without cost they can solve the problem of externalities on their own
The social optimum can be reached through negotiation between the polluter and the victim of the pollution
Private solutions do not always work due to high transaction costs and a large number of interested parties

Thailand’s Commitments to Paris Agreement

Thailand has committed to a 30% reduction in carbon emissions by 2030
Thailand has committed to carbon neutrality by 2050
Thailand has committed to net zero emissions by 2065
